How to create a new textbox every time previous textbox.text is entered?
View 7 RepliesI'm quite new to VB.net (and VS 2008), so I'm afraid my question might be basic, but I'm not sure how to solve it.I have a winform with three textbox fields and a button. All textbox fields must be filled before the user can click the button to continue. To this end I would like to disable the button as long as there is at least one empty textbox.

Have three event handlers, one for each textbox? Or is there a way I'm not familiar with?
